Answer:
x=216
n=18
m=5
x=-11
Step-by-step explanation:
<u>12= x/18</u>
Can also be written as 12=x÷18. Multiply each side by 18 to isolate x and to find the value of x.
This will cause the equation to look like 12×18=x÷18×18. This will eliminate 18 from the right side of the equation and for 12×18 to equal 216. After simplifying it will equal:
x=216
<u>3=n/6</u>
Can also be written as 3=n÷6. Multiply each side by 6 to isolate n in order to find the value of n.
This will cause the equation to look like 3×6=n÷6×6. After simplifying the equation by causing the 6 on the right side of the equation to cancel out and multipyling 3 and 6 together, it will equal:
n=18
<u>-10=m+(-15)</u>
Add 15 to each side of the equation to find the value of m.
This will cause the equation to look like -10+15=m+(-15)+15. This will cause the 15s on the right side of the equation to cancel out and for the left side of the equation to equal 5. After doing this, the equation will equal:
5=m
<u>-7+x=-18</u>
Add 7 to each side of the equation to isolate x in order to find the value of x.
This will cause the equation to look like -7+7+x=-18+7. This will cancel out the 7s on the left side of the equal and the right side of the equation will equal -11. After using these steps to simplify, the equation will equal:
x=-11
